The Flaming Lips may take avant-garde album packaging to new heights on their next record. During a recent interview with NME, frontman Wayne Coyne let slip certain potential album additions involving Miley Cyrus, and, you guessed it, urine.

Consequences of Sound reports, in the past, the psych-rock Lips, formed in 1983, have included craft beer as well as the blood of collaborators (including Kesha and Erika Badu) in copies of their vinyl editions. When asked what could possibly be next, Coyne told NME, “You can’t really up the ante too much from human blood, but maybe when the beer is your own beer – the beer was made especially for the Flaming Lips and has our influence in its taste and colour. That’s not as insane as having a little bit of Erykah Badu, and Chris Martin’s blood in your records. Probably not as insane as that, but still pretty great. The next record we were talking about releasing was Miley Cyrus and Her Dead Petz record. We’d get a good amount of Miley’s pee and mix it with some glitter and put that in. I think that would up the ante. Don’t you?”

The Flaming Lips are currently on tour in continued support of their fourteenth studio album, Oczy Mlody, which was released in January 2017, with upcoming stops in Eugene, Oregon, Seattle, WA and more.

Coyne also spoke with NME about keeping festival season fresh after so many years of touring. “We like them no matter what they are. We play so many kinds of festivals and I think it makes it a wonderful package to look forward to it instead of the dread in some peoples minds who are thinking ‘oh my god, we have to use those toilets’. I don’t blame people for having that in their minds at all. We love all of it that, as along as the audience is having a good time.”
